Study Notes
Myopia (Nearsightedness)
- Myopia is a defect in which a person can see nearby objects clearly but cannot see distant objects distinctly.
- In a myopic eye, the far point is nearer than infinity, and the person may see clearly up to a distance of a few meters.
- The image of a distant object is formed in front of the retina, not at the retina itself.
- Myopia can arise due to:
- Excessive curvature of the eye lens
- Elongation of the eyeball
- This defect can be corrected by using a concave lens of suitable power.
- A concave lens of suitable power will bring the image back onto the retina, thus correcting the defect.
